Steam & Oak Gas Barrel Sauna 3m Canopy + Anteroom (Electric or Wood-Fired)

NEW: First UK barrel sauna available with gas heat — Steam & Oak × FinSteam

Pick "+ FinSteam Aurora 81 R14S Gas Heater" at checkout and your barrel ships with engineered ventilation built for gas + a bundled FinSteam Aurora 81 R14S gas heater package — ready to light on a UK propane bottle the day it lands. Steam & Oak is the only UK retailer offering this. No electrician, no chimney, no fire to tend. Hot in 15 minutes, turn a dial. The Aurora 81 is the only CE-marked electricity-free sauna gas heater on the European market (FinSteam's stated claim).

Why gas changes the equation

The real cost to your first sauna — gas vs electric

An electric sauna's shelf price isn't the price to your first löyly. A 6.8–9 kW electric heater needs its own dedicated circuit, wired by a qualified electrician and signed off under Part P — typically £800–£1,500, plus the wait to get one booked. The FinSteam gas heater connects to a UK propane bottle outside, like a patio heater: no dedicated circuit, no electrician for portable use, and it's hot on the day it arrives.

The ~£2,000 gap on the shelf narrows to roughly £500–£1,200 once the electrician is in the sum — and the gas sauna doesn't wait on a sparky's diary. (Portable use needs no Gas Safe engineer; a fixed install does. A standard UK 13 kg Calor propane bottle runs the heater for a dozen-plus sessions.)

What "gas-ready" means — engineered vents built into the cabin

The gas variant ships with wooden louvre vents at the FinSteam-specified sizes built in: intake ≥350 cm² low next to the heater (fresh air from outside), exhaust ≥250 cm² high in the opposite corner (discharged to outside). FinSteam exclude plastic disc / twist valves — the gas variant doesn't have those. Vent + heater certified together under EU Reg 2016/426. Electric/wood-fired variants ship with the appropriate vent set for that heat type.

• Barrel shell + canopy + anteroom + alder benches + 8mm tempered glass.

Steam & Oak Barrel Sauna 3m Canopy + Anteroom — pick your heater at checkout

Steam & Oak — one of the very few UK sauna brands that lets you choose gas, wood-fired OR electric on the same listing. Pick at checkout.

The choice (heater options)

• ★ + FinSteam Aurora 81 R14S Gas Heater (UK first) — the new gas option. Details above.
• Shell only — buy the cabin, source your own heater.
• + Electric Harvia PC70 6.8kW — sized for the interior, single-phase ~25A circuit.
• + Electric Harvia PC90 9kW — for faster heat-up.
• + Wood-Fired Etna 12 stove + flue kit — traditional log-fired ritual.

The canopy variant of the 3m barrel — same 3m main room + 0.75m anteroom — with an extended canopy roof that overhangs the door for additional rain shelter. Same capacity + same build quality as the standard 3m, with a different roofline that suits buyers who want more covered outdoor space between the sauna and the open garden.

Running cost + warm-up

Gas (Aurora R14S): ~£1.50-£2.00 per session, 15-20 min heat-up. Electric (Harvia 6.8kW): £1.75-£2.25 per 90-min session, 30 min heat-up. Electric 9kW: £2.00-£2.50 per session. Wood-fired (Etna 12): £2-£4 hardwood logs per session. See our full running-cost breakdown.

Canopy vs porch — which to pick

The canopy-roof variant extends out beyond the door, giving a sheltered transition from outdoor garden into the sauna. The standard 3m has the same main room + anteroom but a more compact roofline — slightly smaller external footprint, slightly less rain shelter at the door. Choose the canopy variant if your garden faces prevailing weather (Atlantic-facing coastal locations, exposed Scottish sites); the standard if you want minimum footprint.

• Benches: Alder, comfortable single-level seating
